Public safety system is a generic term, which combines various means of communications used by law enforcement, first responders and other similar agencies. They include paging systems, two-way mobile relay systems, short messaging systems and many others. This report is dealing with standard trunking radio, which will gradually replace numerous non-standard radios prevailing a couple years ago in the U.S. and Europe. It also shows that Ultra Wide Band (UWB) technology may be a valuable asset for first responders in-building communications, especially in harsh environments. More than this, UWB devices can combine communications with radar, given first responders ability to see even through concrete walls. Get Full Details About This Report >> |
